One image is provided of a landslide near the Monterey-San Luis Obispo County line of Big Sur, California during Feb. 23 and April 6, 2024. The image shows shaded relief topography of the landscape during Feb. 23 and April 6, 2024, and the total topographic change between these dates, which shows both erosion (red) and accretion (blue) of the landscape.

Three images are provided of Mud Creek landslide of Big Sur, California during Feb. 23 and April 6, 2024. The first two images show different oblique perspectives of the landscape topography colored by the actual colors from the photographs. The third image shows shaded relief topography of the landscape during Feb.

Location of (A) Baltimore and (B) Norfolk canyons and adjacent slope environments along the U.S. Mid-Atlantic margin. The bathymetry represents 25 m gridded multibeam data with contour lines at every 100 m. Colors on the bathymetric scale represent depth from shallow (red) to deep (blue).

Suspension-feeder isoscapes of Baltimore (A, C) and Norfolk (B, D) canyons with coral distributions outlined in white. Colors represent the different isotopes with cool colors (blues, greens) for δ¹³C data (A, B) and warm colors (pinks, purples) for δ¹⁵N data (C, D), both in ‰.

This flood staff was installed in Kwigillingok, Alaska. The staff measures in feet above the mean higher high water datum.
